Suno Separate

Separate vocals from instrumentals, or split a track into individual stems.

Overview

Suno Separate offers two modes of audio separation. Vocal separation isolates vocals and instrumentals into two tracks. Full stem splitting decomposes a track into up to 12 individual stems (drums, bass, guitar, piano, etc.). The node requires a Suno Task ID and Audio ID from an upstream Suno node.

Configuration

Field	Type	Default	Description
Separation Type	enum	"separate_vocal"	"separate_vocal" for vocal/instrumental split, "split_stem" for full 12-stem separation.
Task ID	string	""	Suno task ID from an upstream Suno node (required).
Audio ID	string	""	Suno audio ID from an upstream Suno node (required).

Inputs & Outputs

• Inputs: audio – Suno task ID and audio ID from an upstream Suno node
• Outputs: audio – separated audio URL(s)

Output Details

Vocal Separation (separate_vocal):

• vocalUrl – isolated vocal track
• instrumentalUrl – isolated instrumental track

Full Stem Split (split_stem):

• stems – object containing up to 12 individual stem URLs (drums, bass, guitar, piano, vocals, etc.)

  Best Practices

• Start with vocal separation before committing to a full stem split.
• Use vocal separation when you only need to isolate vocals for dubbing, voice changing, or remixing.
• Use full stem splitting when you need granular control over individual instruments for mixing or re-arrangement.
• Connect the vocal output to a Voice Changer or Dubbing node for further processing.
• Connect the instrumental output to Suno Add Vocals to layer new vocals onto the backing track.

Common Use Cases

• Extracting vocals from a song for remixing or sampling.
• Isolating instrumentals for karaoke or background music.
• Decomposing a full mix into stems for re-mixing or mastering.
• Preparing isolated vocal tracks for voice changing or dubbing workflows.
• Creating acapella versions of generated songs.

Tips

• Both Task ID and Audio ID are required – these come from upstream Suno nodes, not from raw audio files.
• For non-Suno audio files, consider using the Audio Isolation node (ElevenLabs Voice Extractor) instead.
• The 12-stem split takes longer than vocal separation – only use it when you need individual instrument control.
• Stem names in the output depend on what the AI detects in the source audio.
